Description

Technical Field

[0001] The invention relates to the technical field of mold cleaning devices, in particular to a cleaning device for repairing a large automobile cover mold. Background Art

[0002] In the process of automobile manufacturing, large panel molds are indispensable and important tools. However, during the use of the mold, the accumulation of pollutants such as grease, iron filings, and dust will lead to problems such as reduced precision and insufficient strength, thus affecting production efficiency and product quality. Therefore, the mold should be cleaned and repaired regularly. At present, when repairing the mold, the inner hole is cleaned by a brush structure. After the grease, iron filings, dust and other pollutants in the inner hole of the mold are removed by the brush, the subsequent repair operation is carried out.

At the top of the seat 303, the positioning plate 305 is inserted into the inside of the power seat 301, and the linkage rod 306 is rotatably connected to the inside of the power seat 301, and the rod body of the linkage rod 306 is provided with a thread on the outside, and the linkage rod 306 is screwed to the inside of the positioning plate 305 through the rod body thread, and the linkage rod 306, the positioning plate 305 and the adaptive transmission block 302 are arranged on the same straight line, the adjusting rod 307 is rotatably connected to the inside of the power seat 301, and the adjusting rod 307 and the linkage rod 306 are connected through a set of bevel gear transmission.

[0041] In the embodiment of the present disclosure, the cleaning brush plate 201, the upper connecting rod 202, and the lower connecting rod 203 together constitute a cleaning module, and the cleaning module is provided with two groups, and the two groups of cleaning modules are symmetrically arranged on both sides of the operating rod 1. The lower connecting rod 203 is located inside the operating rod 1. The shaft outside is provided with a linkage gear 2031, and the two ends of the synchronization shaft 204 are provided with synchronization gears 2041. The synchronization gears 2041 at both ends of the synchronization shaft 204 are respectively meshed with the gear teeth of the linkage gears 2031 of the two lower connecting rods 203 for transmission. In use, when the auxiliary component is in the reset state (that is, after pressing the pressing rod 3012), The two groups of cleaning modules are in a retracted state, that is, the auxiliary components are in a state of minimum inner diameter, which makes it convenient to insert the auxiliary components into the inner hole of the mold for cleaning through the operating rod 1. After releasing the pressing rod 3012, the two groups of cleaning modules can be automatically unfolded and used, and can automatically control the cleaning resistance pressure of the cleaning brush plate 201 on the inner wall of the inner hole of the mold. After that, the cleaning operation can be achieved by rotating and lifting the operating rod 1, which ensures the stability and efficiency of the cleaning operation before the mold is repaired. At the same time, it also avoids the phenomenon of scratching and damaging the inner wall of the mold inner hole due to excessive cleaning pressure, and is stable to use.

[0042] In the embodiment of the present disclosure, a power tension spring 3011 is provided on the top of the power seat 301, and the two ends of the power tension spring 3011 are respectively fixedly connected to the top of the power seat 301 and the inside of the operating rod 1, and a pressing rod 3012 is provided on the top of the power seat 301, and the rod body of the pressing rod 3012 passes through the inside of the operating rod 1. The elastic force of the power tension spring 3011 is greater than the elastic force of the limit top spring 3021 and the functional top spring 3032. In use, after the auxiliary component in the reset state is inserted into the inside of the mold inner hole and the pressing rod 3012 is released, the auxiliary component will be unfolded, pressurized and stabilized in turn. The steps include: pressurization is to increase the contact pressure between the cleaning brush plate 201 and the inner wall of the inner hole of the mold, that is, the cleaning pressure, and voltage stabilization is to always maintain the cleaning pressure within a suitable range regardless of the aperture of the inner hole of the mold, and can adapt to the cleaning operations of the inner holes of molds of different types and specifications, and can automatically trigger the regulation, which is highly flexible. After the auxiliary component in the reset state is inserted into the inner hole of the mold and the pressing rod 3012 is released, the first step is to expand. At this time, the power seat 301 will be pulled up by the power tension spring 3011. Since the cleaning brush plate 201 is not The cleaning brush plate 201 will not contact the inner wall of the hole, so there is no resistance in the deployment action of the cleaning brush plate 201. When the power seat 301 moves up, it can drive the adaptive transmission block 302 to move up synchronously. Under the action of the limit top spring 3021, when the adaptive transmission block 302 moves up, the moving card block 3022 can drive the pressure control seat 303 to move up through the moving card slot 3031. The upper connecting rod 202 of one group of cleaning modules is provided with a retractable gear 2021 on the outside, and the side of the retractable seat 304 is provided with a retractable rack 3041. The retractable gear 2021 and the retractable rack 3041 are meshed for transmission. At this time, the functional top spring 303 The pressure control seat 303 and the expansion and contraction seat 304 are maintained as a whole for use, so that when the pressure control seat 303 moves upward, the expansion and contraction rack 3041 of the expansion and contraction seat 304 and the expansion and contraction gear 2021 can drive the upper connecting rod 202 to rotate to realize the expansion action of the cleaning brush plate 201. At the same time, under the cooperation of the synchronous gear 2041 and the linkage gear 2031, the cleaning brush plates 201 of the two groups of cleaning modules can be synchronously expanded and used to adapt to the subsequent cleaning operation on the inner wall of the hole, and can automatically adapt to the cleaning operation in holes with different apertures, which is flexible and convenient to use.

[0043] In the embodiment of the present disclosure, a functional top spring 3032 is provided on the side of the pressure control seat 303, and the two ends of the functional top spring 3032 are respectively against the top of the pressure control seat 303 and the bottom of the expansion and contraction seat 304. In use, during the expansion process of the cleaning brush plate 201, when the cleaning brush plate 201 hits the inner wall of the inner hole of the mold, the cleaning brush plate 201 will be blocked by the inner wall of the inner hole of the mold and cannot continue to expand, thereby completing the expansion step (action) of the auxiliary component. After that, the auxiliary component will perform the pressurization step. Since the cleaning brush plate 201 is blocked by the inner wall of the inner hole of the mold, it cannot continue to expand. The expansion and contraction seat 304 cannot continue to move, so the upper connecting rod 202 locks the expansion and contraction seat 304 through the cooperation of the expansion and contraction gear 2021 and the expansion and contraction rack 3041, so that the expansion and contraction seat 304 cannot continue to move. Under the continuous pulling of the power tension spring 3011, the power seat 301 can still drive the pressure control seat 303 to continue to move upward by adapting to the transmission block 302. The pressure control seat 303 can compress the functional top spring 3032 when continuing to move upward, thereby increasing the cleaning and resistance pressure of the cleaning brush plate 201 on the inner wall of the mold inner hole, so as to ensure the stable and efficient cleaning of the mold inner hole.

[0044] In the embodiment of the present disclosure, a limiting top spring 3021 is provided on the side of the adaptive transmission block 302, and the two ends of the limiting top spring 3021 are respectively against the side of the positioning plate 305 and the side of the adaptive transmission block 302, a mobile card block 3022 is provided on the top of the adaptive transmission block 302, and a continuous mobile card slot 3031 is provided on the inner side of the pressure control seat 303, the slot cross section of the mobile card slot 3031 and the block cross section of the mobile card block 3022 are both triangular, and under the action of the limiting top spring 3021, the mobile card block 3022 is inserted into the mobile card slot 3 031, in use, the auxiliary component is in the pressurization step, when the cleaning pressure reaches the appropriate range, the cleaning pressure will be greater than the elastic force of the limit top spring 3021, that is, when the pressure control seat 303 continues to move upward, the force required to continue to compress the function top spring 3032 is greater than the elastic force of the limit top spring 3021, and then the auxiliary component will perform the pressure stabilization step. At this time, since the cleaning pressure is greater than the elastic force of the limit top spring 3021, when the power seat 301 moves upward, the block bevel of the moving block 3022 and the slot body of the moving slot 3031 The beveled edges will squeeze and avoid each other, so that the transmission block 302 moves toward the inside of the power seat 301 to hide and compress the limit spring 3021, so that the power seat 301 moves alone and will not continue to drive the pressure control seat 303 to move up synchronously. Moreover, since the moving slots 3031 are continuously arranged, under the action of the limit spring 3021, after the moving block 3022 avoids a moving slot 3031, as the power seat 301 moves, the moving block 3022 will continue to be inserted into the next moving slot 303 in the moving direction. 1, so that the pressure control seat 303 is always controlled in a fixed position and does not move, to avoid the pressure control seat 303 excessively moving under the action of the functional top spring 3032 during the pressure stabilization process, resulting in a decrease in cleaning pressure or failure. It is stable to use. When the power seat 301 moves to the maximum position, the auxiliary component can then clean the inner wall of the mold inner hole. It is easy to use. After the cleaning is completed, the auxiliary component automatically resets after pressing the pressing rod 3012, which is convenient for pulling out and cleaning the subsequent mold inner holes. It is very flexible.

[0045] In the embodiment of the present disclosure, an adjustment avoidance hole 101 is provided at the bottom of the operating rod 1 and is axially aligned with the adjustment rod 307. During use, the setting range of the cleaning pressure can be freely adjusted by the adjustment rod 307. When the adjustment rod 307 is rotated, it can drive the linkage rod 306 to rotate through the bevel gear set. When the linkage rod 306 rotates, it can drive the positioning plate 305 to move and change the use position through the rod body thread. The change in the use position of the positioning plate 305 changes the initial extension length of the limit top spring 3021, thereby changing the pressure control seat 303. When following the power seat 301 to move upward, the limit top spring 3021 maintains the synchronous movement of the pressure control seat 303 and the power seat 301 through elastic force to maximize the compression degree of the functional top spring 3032, that is, the cleaning pressure. It is easy to adjust and has strong adaptability.

[0046] Specific usage and function of this embodiment: In the present invention, when the auxiliary component is in the reset state (i.e. after pressing the pressing rod 3012), the two groups of cleaning modules are in the retracted state, i.e. at this time the auxiliary component is in the state of the minimum inner diameter for use, so that the auxiliary component can be inserted into the inner hole of the mold for cleaning through the operating rod 1, and after releasing the pressing rod 3012, the two groups of cleaning modules can be automatically deployed for use, and can automatically control the cleaning resistance pressure of the cleaning brush plate 201 on the inner wall of the inner hole of the mold, and thereafter the cleaning operation can be achieved by rotating and lifting the operating rod 1, thereby ensuring the stability and efficiency of the cleaning operation before the mold is repaired, and also avoiding the phenomenon of scratching and damaging the inner wall of the inner hole of the mold due to excessive cleaning pressure. The auxiliary component in the reset state is After being inserted into the inner hole of the mold and releasing the pressing rod 3012, the auxiliary component will perform the steps of expansion, pressurization and pressure stabilization in sequence, wherein the pressurization is to increase the contact pressure between the cleaning brush plate 201 and the inner wall of the inner hole of the mold, that is, the cleaning pressure, and the pressure stabilization is to always maintain the cleaning pressure within a suitable range regardless of the aperture of the inner hole of the mold, and can adapt to the cleaning operations of the inner holes of molds of different types and specifications, and can automatically trigger the regulation. After the auxiliary component in the reset state is inserted into the inner hole of the mold and releasing the pressing rod 3012, the first step is to expand. At this time, the power seat 301 will be pulled upward under the action of the power tension spring 3011. Since the cleaning brush plate 201 does not contact the inner wall of the hole at this time, the cleaning There is no resistance in the unfolding action of the cleaning brush plate 201. When the power seat 301 moves up, it can drive the adaptive transmission block 302 to move up synchronously. Under the action of the limit top spring 3021, when the adaptive transmission block 302 moves up, the moving card block 3022 can drive the pressure control seat 303 to move up through the moving card slot 3031. At this time, the functional top spring 3032 maintains the pressure control seat 303 and the retractable seat 304 as a whole. When the pressure control seat 303 moves up, it can drive the upper connecting rod 202 to rotate under the cooperation of the retractable rack 3041 and the retractable gear 2021 of the retractable seat 304 to realize the unfolding action of the cleaning brush plate 201. At the same time, under the cooperation of the synchronous gear 2041 and the linkage gear 2031, the two groups of cleaning modules are The cleaning brush plate 201 can be unfolded and used synchronously to adapt to the subsequent cleaning operation by fitting on the inner wall of the hole, and can automatically adapt to the cleaning operation in holes of different apertures. During the unfolding process of the cleaning brush plate 201, when the cleaning brush plate 201 hits the inner wall of the inner hole of the mold, the cleaning brush plate 201 will be blocked by the inner wall of the inner hole of the mold and cannot be unfolded further, so that the unfolding step (action) of the auxiliary component is completed, and thereafter the auxiliary component will perform the pressurization step. Since the cleaning brush plate 201 is blocked by the inner wall of the inner hole of the mold and cannot move further, the upper connecting rod 202 locks the expansion and contraction seat 304 through the cooperation of the expansion and contraction gear 2021 and the expansion and contraction rack 3041, so that the expansion and contraction seat 304 cannot move further. Under the continuous pulling of the power tension spring 3011,The power seat 301 can still drive the pressure control seat 303 to continue to move upward by adapting to the transmission block 302. The pressure control seat 303 can compress the functional top spring 3032 when continuing to move upward, thereby increasing the cleaning and resistance pressure of the inner wall of the inner hole of the mold of the cleaning brush plate 201 to ensure the stability and efficiency of the cleaning of the inner hole of the mold. In the pressurization step, when the cleaning pressure of the auxiliary component reaches a suitable range, the cleaning pressure will be greater than the elastic force of the limit top spring 3021, that is, when the pressure control seat 303 continues to move upward, the force required to continue to compress the functional top spring 3032 is greater than the elastic force of the limit top spring 3021, and then the auxiliary component will be stable. The pressure step, at this time, because the cleaning pressure is greater than the elastic force of the limit top spring 3021, when the power seat 301 moves up, the block bevel of the moving block 3022 and the groove bevel of the moving slot 3031 will squeeze and avoid each other, so that the transmission block 302 moves toward the inside of the power seat 301 to hide and compress the limit top spring 3021, so that the power seat 301 moves alone and will not continue to drive the pressure control seat 303 to move up synchronously, and because the moving slots 3031 are continuously arranged, under the action of the limit top spring 3021, when the moving block 3022 avoids a moving slot 3031, with the power seat 301 As the seat 301 moves, the moving card block 3022 will continue to be inserted into the inside of the next moving card slot 3031 in the moving direction, so that the pressure control seat 303 is always controlled to be fixed in a fixed position and does not move, to avoid the pressure control seat 303 from excessively moving under the action of the functional top spring 3032 during the pressure stabilization process, resulting in a decrease in cleaning pressure or failure. It is stable to use. When the power seat 301 moves to the maximum position, the auxiliary component can then clean the inner wall of the mold inner hole. It is easy to use. After the cleaning is completed, press the pressing rod 3012 and the auxiliary component will automatically reset, making it easy to pull out and clean the subsequent mold inner holes. Operation, the setting range of cleaning pressure can be freely adjusted and used through the adjustment rod 307. When the adjustment rod 307 is rotated, it can drive the linkage rod 306 to rotate through the bevel gear set. When the linkage rod 306 rotates, it can drive the positioning plate 305 to move and change the use position through the rod body thread. The change of the use position of the positioning plate 305 changes the initial expansion length of the limit top spring 3021, thereby changing the maximum compression degree of the function top spring 3032 by the limit top spring 3021 to maintain the synchronous movement of the pressure control seat 303 and the power seat 301 through elastic force, that is, the cleaning pressure.

[0047] In another embodiment, the outside of the cleaning brush plate 201 can be replaced with a cleaning sponge for use, which can adapt to different cleaning operations of the inner hole of the mold, further improving the adaptability of the device.
